1The 10th, 25th, 50th, 75th, and 90th percentiles designate position within each published series. For example, at the 50th percentile or median, half of the
participating workers receive the same as or more than the benefit shown, and half receive the same as or less than the benefit shown. At the 25th percentile,
one-fourth of the participating workers receive the same or less than the benefit shown. The remaining percentiles follow the same logic.

2The categories are based on the average wage for each occupation surveyed, which may include workers with earnings both above and below the threshold.
The average wages are based on the estimates published in the "National Compensation Survey: Occupational Earnings in the United States, 2009." See Technical
Note for more details.

NOTE: Because of rounding, sums of individual items may not equal totals. Dash indicates no workers in this category or data did not meet publication criteria. For
definitions of major plans, key provisions, and related terms, see the "Glossary of Employee Benefit Terms" at www.bls.gov/ncs/ebs/glossary20092010.htm.
